5 A 0.400-g sample of toothpaste was boiled with a 50.00 mL solution containing citrate buffer and NaCl to extract the fluoride ion. After cooling, the solution was diluted to exactly 100.00 mL. The potential of a selective ion/calomel system in a 25.00 mL aliquot of the sample was found to be -0.1823 V. Addition of 5.00 mL of a solution containing 0.00107 mg F/mL caused the potential to change to -0.2446V. Calculate the weight-percent F in the sample
